3.5.3 Calculating the motor / control data
Internal motor / control data is calculated using parameter P0340 or, indirectly
using parameter P3900 (refer to Section 3.5.2) or P1910 (refer to Section 3.5.4).
The functionality of parameter P0340 can, for example, if the motor weight or the
stator resistance is known. The following settings are possible for P0340:
0 No
calculation
1 Complete parameterization
For the complete parameterization (P0340 = 1), in addition to the motor / control
parameters, parameters are also pre-assigned which refer to the motor rated data
(e.g. torque limits and reference quantities for interface signals).

NOTE
When exiting the quick commissioning with P3900 > 0 (refer to Section 3.5.2),
internally P0340 is set to 1 (complete parameterization).
For the motor data identification (refer to Section 3.5.4), after the measurement
has been completed, internally P0340 is set to 3.
